Machine for paring

MACHINE FOR PAR/ING APPLES.

Specification of Letters Patent No. 15,148, dated June 17, 1856.

To all whom t may concern Be it known that I, Jol-IN D. SEAGRAVE, of the city and county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Apple-Paring Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the drawings herewith presented and to the letters of reference marked thereon.

To construct my improved apple parer, I make a frame A, with upright pieces to support shafts B, C, D, and wheel F. On one end of shaft B, put the fork G or instrument to hold the article to be pared and on the other the small gear H. On one end of shaft C, put the crank wheel K, extending beyond the wheel H, and made with a rim with teeth on its inside to work into the teeth of H and drive it in the same direction with a velocity of about 9 to 2; on the other end of C put the bevel wheel I, fitted to drive the wheel F which I make a little more than twice the size of wheel I, and hang it so as to work freely with it. On the back of wheel F make a set of teeth extending about four fifths of a circle (one of said teeth being made larger than the others, leaving the remainder of the circle clear. On the shaft D put a segment or half wheel M having a slot O for the rod P to play in and with the same number of teeth as are placed on the back of wheel F to drive it. On D I also put the spring N, one endv of which is fastened to it and the other to the upright of frame A and arranged to throw or turn the shaft D and wheel M over toward F. The other end of D is turned at nearly a right angle and flattened to allow the. end of rod P to pass through and be held by it. The rod P I make long enough to hold the edge of the knife in the knife-holder K which is fastened on the end of P, over the center of fork G. In the rod P near where it passes through the slot O, in wheel M, I insert a staple or eye T to which attach the spring S, and in the wheel M put a pin to hold the other end of spring S so that it shall F which in proper time gives the segment wheel M a half revolution nearly, carrying the knife holder R over the article to be pared, the spring S attaining most any size to be placed under the knife and holding the knife pressed on to its surface. The space on the back of wheel F then allows Ythe spring N to throw back the wheel M, etc.; and were the articles always true (to be pared) this would be the whole, but to pare uneven surfaces it is necessary for the knife holder R to turn either way. For this purpose the rod P is allowed to turn in D and the spring S is attached to the eye, T, to return it to position again, making the spring S perform the two actions, the one, to hold or draw the rod P toward the center of wheel M, the other, to hold or return the knife holder to position, the spring S may be attached by any other equivalent means to P, or the end passed through it, though I prefer the eye or staple, T.

It will be seen that by a little more than two turns of the crank wheel K the machine has performed its whole operation, or in other words, but a little more than two turns are necessary to pare any moderate sized article by means of this combination.

I do not claim the allowing the knife holder to turn either way as I am aware that has been done. But

I claim- The attaching the spring S to the rod P so as. to hold or return the knife to nearly rightvangles to the line of motion ofP to or from the center of M, as above described.
